I am getting undeliverable sending emails to multiple addresses. I sent the emails in question many times in past with no problems.  I am using Microsoft Office Professional Plus 2024, Outlook.

Error: You do not have the permission to send the message on behalf of the specified user.

I test by sending an email to my other email addresses

Same problem

I have sent emails many times in the past
